Internet connection sharing allows several machines to access the Internet through a single network connection. This method called NAT (Network Address Translation).

If you want to use NAT, you need at least two or more network devices in your machine. If you only have one device you can’t enable the internet connection sharing from Firewall > Run Wizard.

You can enable both the NAT and DHCP via Run Wizard without configure anything.

For outsider, they will see your PCs as a single machine with a single IP address.

Firestarter Policy

Inbound traffic Policy -> control incoming traffic from the internet and LAN to the firewall.

Outbound traffic Policy -> control outgoing traffic to the internet from the firewall and any LAN clients.

Enabling the DHCP Service

Firestarter does not itself include a DHCP server, it depends on the underlying system to provide this feature. If a DHCP binary is not detected on the system, the DHCP controls will remain inactive. You can install using command: taufanlubis@zyrex:~$ sudo apt-get install dhcp
